Ephesians 2:2

Wherein in time past ye walked Sins and transgressions are a road or path, in which all unconverted sinners walk; and this path is a dark, crooked, and broad one, which leads to destruction and death, and yet is their own way, which they choose, approve of, and delight to walk in; and walking in it denotes a continued series of sinning, an obstinate persisting in it, a progress in iniquity, and pleasure therein: and the time of walking in this path, being said to be in time past, shows that the elect of. God before conversion, walk in the same road that others do; and that conversion is a turning out of this way; and that when persons are converted, the course of their walking is altered, which before was

according to the course of this worldmeaning this world, in distinction from the world to come, or the present age, in which the apostle lived, and designs the men of it; and the course of it is their custom, manner, and way of life; to which God's elect, during their state of unregeneracy, conform, both with respect to conversation and religious worship: great is the force that prevailing customs have over men; it is one branch of redemption by Christ, to deliver men from this present evil world, and to free them from a vain conversation in it; and it is only the grace of God that effectually teaches to deny the lusts of it; and it is only owing to the prevalent intercession and power of Christ, that even converted persons are kept from the evil of it:

according to the prince of the power of the air: which is not to be understood of any supposed power the devil has over the air, by divine permission, to raise winds, but of a posse, or body of devils, who have their residence in the air; for it was not only the notion of the Jews F13, that there are noxious and accusing spirits, who fly about (rywab) , "in the air", and that there is no space between the earth and the firmament free, and that the whole is full of a multitude of them; but also it was the opinion of the Chaldeans {n}, and of Pythagoras F15, and Plato F16, that the air is full of demons: now there is a prince who is at the head of these, called Beelzebub, the prince of devils, or the lord of a fly, for the devils under him are as so many flies in the air, ( Matthew 12:24 ) and by the Jews called F17, (ayxwrd Nwhbr) , "the prince of spirits"; and is here styled, the Spirit that now worketh in the children of disobedience; by which spirit is meant, not the lesser devils that are under the prince, nor the spirit of the world which comes from him, and is not of God; but Satan himself, who is a spirit, and an evil, and an unclean one; and who operates powerfully in unbelievers, for they are meant by children of disobedience, or unbelief; just as (atwnmyhm ynb) , "children of faith" F18, in the Jewish dialect, designs believers; and over these Satan has great influence, especially the reprobate part of them; whose minds he blinds, and whose hearts he fills, and puts it into them to do the worst of crimes; and indeed, he has great power over the elect themselves, while in unbelief, and leads them captive at his will; and these may be said in their unregeneracy to walk after him, when they imitate him, and do his lusts, and comply with what he suggests, dictates to them, or tempts them to.
